我最近一直在尝试使用 Chef。我想尝试使用 chef-solo 重建我的个人 Web 服务器。这是一个运行 Amazon 64 位 Linux AMI 的 AWS 实例。
我的第一个目标是安装 nginx。我已经克隆了 Opscode cookbook 存储库，并且正在使用他们的 nginx 手册。
我的问题看来 chef-solo 在启动该过程后无法找到模板。
我使用的命令是
chef-solo -j /etc/chef/dna.json
dna.json
{
"nginx": {
"user": "ec2-user"
},
"recipes": [ "nginx" ]
}
solo.rb
file_cache_path "/var/chef-solo"
cookbook_path "/var/chef-solo/cookbooks"
...输出
[root@ip-10-202-221-135 chef-solo]# chef-solo -j /etc/chef/dna.json
/usr/lib64/ruby/gems/1.9.1/gems/systemu-2.2.0/lib/systemu.rb:29: Use RbConfig instead of obsolete and deprecated Config.

我做错了什么？
答案1
为了修复这个问题你应该将它添加到你的 nginx 默认配方的开头：
directory "/etc/nginx/sites-available" do
owner "root"
group "root"
mode "0755"
end
值得一提的是，我一直在使用 Chef (Hosted)、EC2 和 Amazon Linux 做同样的事情。我花了一段时间，但我发现自己动手几乎总是更容易。我现在有十几个正在使用的配方，并且删除了最初尝试的所有 Opscode 共享配方。
事实上，我的 nginx 默认配方只有一行：
`package "nginx"`
因此，一种方法是先将其安装在您的服务器上，yum install nginx然后获取它创建的默认配置文件。将其作为模板带回您的食谱，并输入 ERB 行以根据您的需要自定义任何值。
答案2
看起来树中的目录/etc/nginx/sites-available不存在并且应该被创建。
如果您想要添加到 opscode 配方中，可以按照以下方法让 chef 为您创建目录：
